leitkurve 13+4x-x^2

Lösung

leitkurve

13 + 4 x - x^{2}

Lösung

y = \frac{69}{4}

Schritte zur Lösung

Rewrite

y = 13 + 4 x - x^{2}

in the standard form

4 (- \frac{1}{4}) (y - 17) = (x - 2)^{2}

(h, k) = (2, 17), p = - \frac{1}{4}

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance

- p

from the center

(2, 17)

y-coordinate

y = 17 - p

y = 17 - (- \frac{1}{4})

Fasse zusammen

y = \frac{69}{4}
